Case study on implementation
It is used on No. 4 lines of certain subway across in the design and construction of existing vcehicular tunnel.
Technical difficult points are：
1. No. 4 line running tunnels of new subway and it is existing runed highway tunnel structure between clear distance it is small, such as take direct excavation
Tunnel then can adversely affect existing highway tunnel structure.
2. it needs to abolish the shadow that part existing tunnel system supporting anchor pole will be certain to existing tunnel structure and operation generation
It rings, therefore how to refine and solve to have an impact existing vcehicular tunnel when No. 4 line running tunnels of new subway excavate, between the two
Design of Reinforcement and transformation will be to increasing economic results in society, reducing risk, influence degree of existing tunnel operation etc. to closing weight
It will.
After excessive kind of demonstration design, design and construction use inventive method illustrated herein.Forms of protection uses pre-pouring grout, surpasses
The support reinforcement form of preceding ductule and steel tube shed.The operation monitoring data of site operation experience, monitoring data and existing tunnel
Fully prove：The position of the structure of existing tunnel can be strictly controlled using steel tube shed reinforcing new subway tunnel bottom soil body technology
Move deformation, it is ensured that the safe normal operation in tunnel；Using the pipe canopy reinforcement interlayer soil body, structural damage is avoided；Utilize static(al)
Cutting scheme noise is small, favorable environment protection and civilized construction.
The present invention can be widely popularized in the crossing project up and down of newly built tunnels, across existing municipal administration on especially suitable small interval
Tunnel Engineering can make engineering safer, economical.
